My dett runs good but won't take full throtle, AFR gauge says it goes off the chart lean.

 

have your checked your O2 sensors? and check your TPS too

 

ya. tps and o2 sensors are pretty good places to start testing things

 

Is that a wideband O2 sensor? If it isn't, remove it and throw it in the garbage because it's not telling you anything (at WOT, the O2 sensors don't give meaningful readings, so a narrowband gauge is nothing but a fancy disco light).

 

I've checked the tps voltage it was pretty close and it is a wideband sensor. I'll check the o2. I put the wideband in place of the right side o2 and tied the wires back to the left o2. If you go at it slow it'll rev and stay around 15.0.

 

I've gone to checking the pinout voltage at the ECU and Ive found problems there. The voltage at ecu power pin while running is 13.75 and shouldn't be but like 8. I'm gonna go back thru the wiring and re-check myself, I had to do alot of figuring to get the dett in my z31, looks like a gotta little more to do.
